About the DCS-200

HDCP stands for High-Bandwidth Digital Content Protection, an industry-wide copy 
protection scheme that is used to prevent the potential interception of digital data between 
the source (e.g., a Blu-Ray player) and the target display (e.g., an HDCP compliant display 
or monitor).  The HDCP format was designed by Intel

®

, and it uses an “authentication and 

key exchange” procedure to accomplish the required protection.  For proper 
implementation, products that are compatible with the HDCP format require a secure 
connection to a compliant display, such as a projector or monitor.    

In applications in which a DCS-200 is used, when an HDCP compliant device is connected 
to the DCS-200, an HDCP “session” is created.  In this session (which is transparent to the 
user), “keys” are exchanged between the source device (e.g., a Blu-Ray player) and the 
HDCP compliant display.  

The source device queries the display to ensure that the equipment is HDCP compliant 
before video is shown.  Non-HDCP equipment such as PCs will work with any DVI 
compliant display, but HDCP compliant equipment only shows “protected” content on 
HDCP compliant displays.  

Please note the following important points:

When an HDCP compliant device is connected to the DCS-200 and that specific 
input is selected, the Status Menu indicates if HDCP is enabled.

If the “session” determines that the target display device is non-HDCP compliant 
(e.g., if the user is attempting to make an illegal copy on an external recorder), an 
error message appears on the DCS-200’s Status Menu, indicating that video 
cannot be shown.

HDCP compliant repeaters cannot be connected to the output of the DCS-200, as 
the DCS-200 must be the last device in the HDCP "chain" — prior to the HDCP 
compliant display.  If an HDCP repeater is connected, the message “HDCP 
Violation” appears on the Status Menu.  In Chapter 4, refer to the “

section on page 44 for additional details.
